Mingjiada Supply ST Automotive GNSS Positioning Module - Supply TESEO-VIC6A Quad-Bands TeseoVI GNSS Module

TESEO-VIC6A Quad-Band Teseo VI GNSS Module — Mingjiada Electronics Supplies ST’s Automotive-Grade GNSS Positioning Module
Amid the rapid development of vehicle intelligence and autonomous driving, high-precision, highly reliable positioning modules have become a core necessity. Mingjiada Electronics supplies the TESEO-VIC6A, launched by STMicroelectronics (ST) — an automotive-grade positioning module that integrates quad-band, multi-constellation GNSS reception with a six-axis inertial sensor, providing sub-metre positioning accuracy for demanding applications such as ADAS, in-vehicle navigation and autonomous driving.

I. Product Overview
The TESEO-VIC6A is an easy-to-use, quad-frequency, multi-constellation Global Navigation Satellite System (GNSS) standalone module from STMicroelectronics’ Teseo VI series. It incorporates the Teseo VI single-chip standalone positioning receiver IC and supports simultaneous operation across six major constellations: GPS, Galileo, GLONASS, BeiDou, QZSS and NavIC (formerly IRNSS). This module delivers the proven high precision and reliability of the Teseo VI chip to users, whilst its embedded firmware and comprehensive evaluation environment significantly reduce development time.
As an AEC-Q104 automotive-grade certified solution, the TESEO-VIC6A operates within a temperature range of –40°C to +105°C, enabling it to cope effortlessly with the demanding environments of automotive applications.

III. Key Features (TESEO-VIC6A)
1. Simultaneous Reception of Four-Band, Multi-Constellation Signals
The TESEO-VIC6A supports four-band GNSS signal reception and can simultaneously track six major constellations: GPS, Galileo, GLONASS, BeiDou, QZSS, and NavIC. Thanks to its multi-constellation fusion positioning capability, the module maintains stable and accurate positioning output even in complex environments.
2. On-Board TCXO + RTC: Balancing Accuracy and Speed
The TESEO-VIC6A features an on-board temperature-compensated crystal oscillator (TCXO) to achieve exceptional positioning accuracy. It is also equipped with a dedicated real-time clock (RTC) oscillator, which significantly reduces time-to-first-fix (TTFF). Cold start TTFF is as fast as 29 seconds, while hot start TTFF takes only 1.8 seconds.
3. Embedded Flash, Supporting Assisted GNSS
Thanks to its embedded Flash memory, the TESEO-VIC6A supports multiple additional features, including 7-day automatic Assisted GNSS and real-time Assisted GNSS. It also supports firmware configuration and firmware upgrades.
4. Six-Axis Inertial Sensing + Dead Reckoning
The TESEO-VIC6A features a built-in STMicroelectronics automotive-grade 6-axis inertial sensor (3-axis accelerometer + 3-axis gyroscope) and supports ST Teseo-DRAW (Automotive Dead Reckoning) technology. When GNSS signals are temporarily lost (e.g., in tunnels or underground parking garages), inertial navigation seamlessly takes over to ensure uninterrupted positioning.
5. Signal Integrity and Anti-Interference
The TESEO-VIC6A supports signal integrity features and is equipped with anti-interference and anti-spoofing capabilities. It also supports all SBAS satellite-based augmentation systems (including WAAS, EGNOS, MSAS, GAGAN, etc.), further enhancing positioning accuracy and reliability.
6. Extensive Interfaces and Flexible Control
Control is possible via interfaces such as I2C, UART, and GPIO. It supports standard PVT positioning, as well as code phase, carrier phase, and Doppler frequency measurements, meeting the data requirements of high-precision positioning algorithms.

IV. Typical Application Areas
With core advantages such as AEC-Q104 automotive certification, sub-meter positioning accuracy, quad-band multi-constellation fusion, and six-axis inertial dead reckoning, the TESEO-VIC6A is widely used in the following scenarios:
Advanced Driver Assistance Systems (ADAS) — Provides precise positional references for lane-keeping, automatic emergency braking, and other functions
In-Vehicle Navigation and Vehicle-to-Everything (V2X) — Maintains stable positioning in complex environments such as urban canyons
Fleet Management and Logistics Tracking — Enables real-time vehicle location monitoring and route optimization
Autonomous Driving — Provides highly reliable positioning support for high-level autonomous driving
Drones and Robots — Meets precise navigation requirements in highly dynamic environments
